CHIMNEY CAP AND VENTILATOR.

SPECIFICATION forming part of Letters Patent N0. 320,794, dated June 23,1885.

Application filed May 27, 1884.

To all whom it may concern:

Be it known that we, WILLIAM J. KAYSER and CHARLES KAYSER, of Milwaukee,in the county of Milwaukee, and in the State of Wisconsin, have inventedcertain new and useful Improvements in Chimney-Gaps and Ventilators; andwe do hereby declare that the fol lowing is a full, clear, and exactdescription thereof.

Our invention relates to improvements in chimney caps and ventilators,and will be fully described hereinafter.

In the drawings, Figure 1 is an elevation of a chimney-pipe fitted withour improved cap and ventilator. Fig. 2 is a vertical section throughthe center of the same, and Fig. 3 shows the fastenings of our device.

A is the chimney-pipe, which is fastened in any suitable manner on topof the chimney A.

B is a truncated open cone set in an inverted position around the pipeA, and attached thereon, so that its upper half projects above the topof said pipe, while an annular space, a, is left between its lower rimand the periphery of the pipe A.

B is'another open truncated cone set in its upright position around thepipe A, above and opposite the cone B, the distance between the two saidcones B and B being about equal to half the height of the former.

The two cones B B are connected to one another, and are supported aroundthe pipe by means of the supportingpieces O 0, one of which is shown inperspective in Fig. 3. The edges of these supportingpieces G are shapedin a manner to conform to the inclined surfaces of the cones B B and tothe sides of the pipe A, and are provided with flanges c, c, and o Theflange 0, formed on the lower half of the vertical inner edge of each ofthe supporting-pieces O, has about two-thirds of its length bolted orriveted to the pipe, while the upper part of the same is cut and bentout to form the hook c and clasp the top of the pipe A, as shown. Theflange 0, formed on the lower-inclined edge of the supportingpiece 0, isriveted or bolted onto the inner face of the cone B, while the flange 0formed (No model.)

on the upper inclined edge of said piece 0, is

riveted or bolted onto the inner face of the cone B. An open slot, 0, iscut into the vertical inner edges of said pieces 0 G, and in theseslots, which are on a suitable incline, is inserted the lower rim of theshield E, made in the form of a truncated open cone. This shield isdesigned to prevent the deflection into the pipe A of the forced draftcreated in the space a left between the cones B and B.

Around the upper rim of the upper cone, B, are fastened the uprightpieces (Z (Z d, which serve to support the pipe-cap D, made in anysuitable form and with its outer rim projecting sufliciently outwardbeyond the upper edge of the cone B to protect the top of the pipe Afrom return drafts as well as from rain or snow.

Though we have described our cap and ventilator as being formed withcones, it'mnst be understood that the same may be made either square orwith any number of sides, and its dimensions and proportions may bevaried as desired without departing in the least from the spirit of ourinvention.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. In a chimney cap and ventilator, the conibination of the upper andlower truncated cones with supporting-pieces 0, having slots 0, adaptedto receive the edges of the shield, as described.

2. In a chimney cap and ventilator, the combination of the cones B andB, the supportingpicccs 0, having flanges c, c, and c, and open slot 0,and shield E, adapted to fit into theslotsv of the supporting-pieces,and cap D, with fast eningpieces (Z d, substantially as shown anddescribed, and for the purpose set forth.

In testimony that we claim the foregoing we have hereunto set our hands,at Milwaukee, in the county of Milwaukee and State of Wisconsin, in thepresence of two witnesses.
